<p>PROBLEM TO BE SOLVED: To provide a new microscopic system capable of condensing erase light for exciting a molecule in a 1st electronic exciting state to a 2nd electronic exciting state by using a simple and compact optical system in excellent beam profile, making stability and operability high and having excellent super resolution. SOLUTION: This system is equipped with the light source of wavelengthλ1 light for exciting the molecule from a base state to the 1st electronic exciting state, the light source of wavelengthλ2 light for exciting the molecule in the 1st electronic exciting state to the 2nd electronic exciting state or a higher electronic exciting state, a condensing optical system condensing the wavelengthλ1 light and the wavelengthλ2 light on an adjusted sample, and a superposing means for partially superposing an irradiation area by the wavelengthλ1 light and an irradiation area by the wavelengthλ2 light on the adjusted sample. By radiating the wavelengthλ1 light and the wavelengthλ2 light through the superposing means, a light emitting region in the case of de-exciting the molecule from the 1st electronic exciting state to the base state is restrained.</p> |
